ELECTRIC SADIRON.

Specification of Letters Patent. I Patented J une- 29, 192a Applicationfiled 0ct'ob'er13, 1914. Serial No. 864,718.

To all whom it may concern:

' Be it known that I, FRANK THORNTON, J r.,

a citizen of the United States, and a resident of Pittsburgh, in thecounty of Allegheny and State of Pennsylvania, have invented a new anduseful Improvement in Electric Sadirons, of which the following is aspecification. I

My invention relates to electric heating apparatus, and it has specialreference to electric sad irons and the like.

The object of my invention is to pro vide a device of theabove-indicated character which shall be simple and durable inconstruction and which shall embody novel features that add to itsconvenience .without increasing the number of its parts or its cost ofmanufacture.

In the accompanying drawing, Figure 1 is a side elevational view, withparts shown in-longitudinal section showing a sad iron.

constructed in'accordance with my invention. Fig. 2 is a rearelevational view of the sad iron illustrated in Fig. 1, and Fig.

3 is a transverse sectional view taken alongmember 8 detachably securedto the strap" 5 and provided with a suitable cord 9 for attachment to asource of electric energy.

The heating element 2 may be of any convenient form and forms no part ofmy present invention. As shown, the element 2 comprises a plate 10 ofresistance material inclosed between sheets 11 and 12 of insulatingmaterial, such as mica.

Adjacent to the rear portion of the heatstorage member 3, and attachedthereto by means of bolts 13 and 14, is a block 15, of

heat-insulating and electrical insulating material, in which areembedded or to which are attached terminal conductors 16 which block 15by means of screws 17 and w ich areintimately connected at'18 tothe-heating element 2. If desired, the insulatin 'block 15 may be madein a plurality o sections, held together by means of the bolts 13 orotherwise. The block 15 extends beyond the heel of the iron, and itscontouris such 1 forms of terminal devices may be substituted for it. Insome cases, the terminal device may cooperate with the block 15 to forma heel stand, as shown in the drawing,

or the handle 4 may be extended to the rear sufficiently to form part ofthe heel-stand.

As shown in the drawing, the terminal device 8 1s .detachably secured tothe strap 5 by means of a clamp 20, the strap 5 being cut away at 21 topermit the clamp 20 to be slipped from the strap.

In order. to inclose the heating element completely within the body ofthe iron without the use of a separate cover, the

working member 1 and the heat-storage member 3 are provided with acooperating groove and rib. As shown in the drawing, a depending rib 22is formed around the lower edges of the heat-storage member 3,

and a corresponding recess or rabbet 23 is formed around the upperedges-of the working member 1. It is obvious that the rib may be formedin the working member and the groove in the heat-storage member, if

desired.

The features of my invention which render it superior to the known formsof electrically heated sad irons are the construction just described,which permits the heat- ;ing element to be inclosed between two memberswithout the use of an additional casing or cover, and second, theprovision of a single body of heat-insulating and electrical insulatingmaterial, which serves the double function of receiving the ter- Iminals of the heating element and of pro-' viding a heel stand for theiron.

It is obvious that the structure which I have shown and described may bevariously modified by-persons skilled in the art to which my invention'appertains, and it is therefore to be understood that my inven tion isnot restricted to the precise embodiment herein shown and described, butis limited claims.

I claim as my invention: 1. A terminal device for electric heating only:by the scope ofthe appended the heel of the said body portion and amassof heatinsulating material in which the said terminals are embeddedand which is provided with a fiat. surface adapted to serve as part of aheel stand for the iron.

3. An electric sad iron comprising a base member, a body member composedof heatstorage 'material, a heating element disposed between, andelectrically insulated from, said members in a manner to permit heattransfer between the heating element and the members, a cooperating riband a depression being formed on the members for inclosing the heatingelement, a handle 1 mounted onthe body member and bolts passing througha portion of said handle and the body member into the base member forsecuring the, parts of the iron together.

4. An electric sad-iron comprising a base member provided with a recessaround its upper edges, a body member composed of heat-storage materialhaving a rib around its lower edges adapted to be received in the recessin the base member, a heating element disposed between said members andelectrically insulated from the members in a manner to permit a freetransfer of heat, and bolts passing through the body member and theheating element into the base mem ber for securing the partsof'the irontogether. v

5. An electric sad iron comprising a body portion, a handle, an electricterminal device rigidly associated With the heel of the said bodyportion and including a body of heat-insulating material, and a terminaldevice removably secured to the said handle, the said fixed and movableterminal devices being adaptedto cooperate to form a, heel stand for theiron.

I In testimony whereof, I have hereunto subscribed my name this 28th dayof September, 1919.
